Description of problem:
When playing OpenGL games full screen, there is a 1-pixel border of
garbage on the right and bottom sides of the screen. This wasn't
there on my previous Red Hat installation, 7.3.
This does not occur for non OpenGL programs, such as Adobe Acrobat in
full screen which is fine. So the bug is similar but different than
Note that the bug could be in the kernel DRI module for Radeon, as well
as in the X server.
My card is a "ATI Technologies Inc Radeon RV200 QW [Radeon 7500]"
and my north bridge (for AGP) is "SiS645DX Host & Memory & AGP
Controller". I setup the graphics at a resolution of 1600x1200.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Configure an OpenGL game full screen at 1600x1200
Actual Results: 1-pixel border of garbage on the right and bottom
sides of the screen
Expected Results: no such border
I can see this on my Radeon 9000 Pro when running the "pulsar"
screeensaver. In this case, when ends of the rotating planes in the
screensaver go offscreen on the bottom and right-hand side of the
screen, there is a 1-pixel border of garbage...
Very unlikely to be a kernel bug at all. More likely than not,
it would be a bug in radeon_dri.so 3D driver. Please attach your
XFree86 log, config file, and /var/log/messages to the bug report
as individual uncompressed files using the file attachment link
Can you do the same also please?
Hmmm, I tried to replicate it on my fully-updated FC1 home box last
night, and I couldn't. I also tried to replicate it on my FC2t1 test
box at work, and no dice, either.
I *know* I've seen this bug, and could've sworn it was in the FC1
timeframe. I'm going to put the initial FC1 release on my test box,
and see what happens...
Hmmm, the initial FC1 release doesn't do it on my test box. Sorry, I
guess I'm outta luck on this one...
Ed) Are you using 1600x1200 to try to reproduce? It's possible it
could be a bug specific to a particular screen size, possibly an off
by one bug in mode specific code or somesuch.
Guru) Can you test this in other video modes also?
No, I was trying 1280x1024 at home, and 1024x768 at work. These
resolutions have been what I've been using for forever, so it doesn't
